Yes, I use the same account. I never actually logged in any other way, than with my Google account. Today, I did what I always do and it created the new account. I changed the username to laurin1 (thought maybe that was a change to my account.)

For some reason today, when I logged in it was with my gmail account (I usually use the other one) and YouTrack picked it up as a different account. I tried to login with the other address, but that doesn't work (still logs into the new account.)

I'm opening YouTrack tickets in both accounts, and putting all of this information in it. I can work around it right now, but I need the new account deleted (or merged with my old account, however that happens.)

I merged your two accounts and set your email to "laur****@gmail.com". You can now re-login with your google OpenID and this should be your "old" account. After that, you can change e-mail back to whatever address you want.
